SPECIFICATION forming part of Letters Patent No. 602,904, dated April 26, 1898.

Application filed May 6, 1897- Serial No. 635,311. (No model.)

To all whom it may concern.-

Be it known that we, FRANK A. HILL and NVILLIAM E. SHEHAN, citizens of the United States, residing in the city of St. Louis, State of Missouri, have invented a certain new and useful Improvementin Attachments for Linotype-Machines, of which the followin g is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a view of a portion of the vise and knife-block of a linotype-machine, showing our improved attachment attached to the knife-block. Fig. 2 is a horizontal sectional view through the knife-block and its associate parts, showing our improved attachment in an operative position; and Figs. 3, 4, and 5 are detailed views of slugs with which the movable knife cooperates.

This invention relates to a new and useful improvementin attachments forlinotype-machines, and particularly to that part of the linotype-machine which gages the ribs on the issuing slugs after they have been molded. For the purpose of separating the slugs certain distances apart, which is commonly known as leading, we have devised this attachment,by which we are enabledto instantly change the mold-knives (without the assistance of a machinist) by raising or lowering a small lever placed within easy reach of the operator, whereby the operator can at will set solid or thin (one point) or thick (two points) leaded type.

The object of this invention is to provide mechanism for readily and quickly adjusting the movable knife so that said knife will shave the ribs on the slugs as desired.

Another object in view is to provide means for smoothing down the burs or fins formed on the ribbed side of the slug, which are present when the ribs are left on the slug or are but partially removed.

With these objects in view the invention consists in the construction, arrangement, and combination of the several parts for accomplishing the above, all as will hereinafter be described and afterward more fully point.- ed out in the claims.

In the drawings, A indicates the mold-disk,

B the vise, C the galley, andD the knife-block, all such parts being of ordinary construction.

E indicates the stationary knife, mounted on the vise.

F indicates the movable knife, preferably mounted in a recess in the face of the knifeblock. v

G indicates screws formed with right and left hand threads engaging, respectively, the movable knife and the knife-block.

Hindicates arms mounted on the outer ends of screws G.

I indicates a link con neciin g the outer ends of arms H.

J indicates a sector or segment arranged on the side face of the knife-block D.

K indicates a handle pivoted to the inner end of sector J, said handle being provided with a retainin g-pawl for engaging the notches in the periphery of sector J.

L indicates a pin fixed in handle K and engaging link I.

From the above description it will be obvious that when handle K is raised or lowered it will partially rotate, through its connected mechanism, the screws G, and said screws will impart a lateral movement to the movable knife F, forcing said knife toward or from the stationary knife E. As seen in Fig. 2, knife F is, adjusted relative to knife E, so that the slug after being passed between the cutting edges of said knives will be solid matter. The ribs on the side of the slug are therefore shown as being shaved off almost entirely. By adjusting the handle K into another notchon sector J, so that knife F is moved farther away from knife E, a lesser portion of the ribs on the slugs will be shaved ofi, as shown in Fig. 4. By adjusting the handle K to another notch on sector J the knife F will be moved so farfrom knifeEthat the slug will practically pass between the two blades intact, knife F removing only a sumcient portion of the ribs to make the slugs of uniform thickness throughout their length.

It has been found from experience that when the slug is issued from the machine with full-sized ribs a fin or bur will be left near the type edge of the slug and between the ribs, as shown in Fig. 3, and while this fin is ported in the inner face of the knife-block for not a seriousobjection to the slug it deteriorates from its appearance when in the galley. We have therefore grooved the plate L, which fits in the inside face of the knife-block, to permit these ribs to pass in said groove, (shown at 1,) so that the outer edge of said plate, which is held closeto the Vise by a spring Z, will rub against the plain surface of the slug and smooth down this fin or bur. i We are aware that many minor changes in the construction, arrangement, and combination of the several parts of our device can be made and substituted for those herein shown and described without in the least dewe claim, and desire to secure by Letters Patent, is

1. In a linotype-machine, the combination with" the knife-block, of the stationary and movableknives, and a plate yieldingly supengaging the slug as it issues from the machine and smoothing down any fins or burs which may be present on the type edge of the slug, said plate being provided with a plural-- ity of grooves arranged in line with the ribs on the slug, whereby said ribs fit into the grooves and permit the body portion of the slug to fit close against the plate, as the slug is forced past the plate; substantially as described.

2. The combination with a knife-block, of a movable knife mounted therein, of a right and left hand screw which engages the movable knife and the knife-block at its differently-threaded portions respectively, arms on the ends of said screws, a link connecting said arms, a lever engaging said link for moving the same and the screws simultaneously,

and a sector with which said lever cooperates;
